I also cracked my screen with this method ,not to be outdone I bought another phone for the screen .this time I used a thin guitar pick which I ran along the edges and around the phone carefully , it took a while but eventually worked the screen loose ( the glue area is small but still strong as I learned the first time) any way when the screen is loose enough , make sure the tabs on the inside cover are also loose (using the pick) I was able to then pop out the screen and replaced the mobo I have a nice new phone now ! Bottom line is don't pry on the screen it will crack loosen it completely and it will pop out nicely . Good luck .

This is not hard to do, but it is dangerous. The author is correct, no heat gun is necessary but it's easier with a heat gun or low or a hair drier on high. Don't use a metal blade, only use a guitar pick or plastic spluge. Be patient and do resist any temptation to pry *deeper*. Just keep prying shallow and horizontally. You may have to go around the perimeter several times but you will succeed.

As soon as you rush, decide you have to pry harder or let a tool go a millimeter or two *deeper* that is what will kill your LCD.

I meant to add.. there are two ways to kill the LCD or possibly crack the glass. By going too deep in the seam. So stay shallow. But you can also damage the LCD by putting too much sideways horizontal stress on it too. So it helps to keep moderate pressure down on the top of the phone so that most of your prying sideways force goes towards deflecting the bezel outward and thereby dislodging the adhesive seal. So "pinch" the phone by holding the top and bottom between your fingers of one hand. Or set the phone on a flat surface and press down on the top (glass) of the phone moderately to try and keep the glass and LCD sandwich in place while you pry as gently as possible sideways and outward to dislodge that adhesive seal.

Push on the battery housing to separate the midframe from the display assembly.

You will have to apply a reasonable amount of pressure to separate the two parts.

If your new midframe does not come with a headphone jack assembly, you'll need to transfer the one from the old midframe into the new one. It can be pried loose with plastic opening tools, as it is held in place with several plastic pins.

If you want to break the LCD or if it is already broken, poke both your thumbs into the battery pocket as shown in the picture. This may snap off the back, but it will also crack the LCD. The better way is to put your right thumb into the top right corner of the battery well and your left thumb on the SC card slot, then hook your fingernails on the top corners and side edges of the rear housing and push gently to separate it from the midframe.

Remember, the LCD hinges at the top, the rear housing hinges at the bottom. Once you see how the charge port fits into the recess at the bottom of the rear housing, you will understand what I mean.

This Note 4 rear housing fits tighter than previous Samsungs such as the S3 & S4 where you can take out the screws and then pop off the rear housing easily with your fingernails. Be very careful around the touch button flex cables at the bottom or be prepared to replace that assembly. It is cheap, so you may want to go ahead and order that when you get an LCD assembly.

Thank you, very helpful in my swap out of the assembly. I also had to remove the headphone assembly and reinstall it into my new mid-frame. I added a step 5 to this user guide with a new image of the part that must go into the replacement mid-frame.

I've never been able to put these 2 ribbon cables back to the motherboard without first separating the AMOLED/digitizer screen assembly from the mid frame. What is the easiest way to get these ribbon cables plugged back in?

I have done a few Note 4 motherboard replacements...about 10 or so. I have not been able to simply "To reassemble your device, follow these instructions in reverse order." I always have to separate the screen from the mid frame in order to plug the 2 top ribbon cables back to the motherboard. I can't figure out a way to get the ribbon cables plugged back in without doing so. This screen separation process is very tedious, long, and stressful as it could crack the AMOLED screen if you're not careful. If someone can show me exactly how to simply, "To reassemble your device, follow these instructions in reverse order" it'll make it a lot easier for me. Thanks.

As for getting the flex cables to snap back in; You basically need to add about a quarter millimeter thickness to the back of the foam behind the amoled display and s-pen flex cable connectors. I apply a strip of double sided tape to the foam, the same width and length, but leave the tape's protective paper in tact so you are not taping the connectors to the back of the display. This will move the connector up "just" enough to be able to snap it into the socket. You'll want to press firmly against the screen and logic board at each connector point, but don't force it. The connectors for the rear camera and usb flex won't need extra tape, but connect in the same manner.

Hey guys,for those of you that couldn`t reassemble the phone after taking the display out and in this way you had to separate the screen from the mid frame i have an advice! In fact 2.First one would be to try this way :https://www.youtube.com/watch?v=OUDgGaFc... In this video (after 10 min or so you can see a good tip if you replace your display with a new one).As in this video you can use a memory card when you try to get the conector back in it s place.Usualy if you center the connector properly it will work for sure in almost all the time!

As already pointed before,If you cannot get it done this way there is the second strategy.I manage to reconnect that little devil so simple that i thought it`s a joke.All you need is a tiny piece of adhesive tape(not necessary double adhesive,but it doesn`t matter because you will use only one part and the other i think it`s better to not unpeel it ).I used one from Bison(double tape fix),cheap and practical,check on google for it.So you need 2-3 mm of this tape,cut it in a small band and adhere it under the connector spongy thing.In this way the connector will be raised a little and of course will fit better in it`s place when you press the motherboard(specially with a card inserted as in that vid up ).Good luck!

This is something i would like to know. My note 4. Went out and keeps powercycling. The store said it was the motherboard cause it gets stuck on the powering up screen that says samsung galaxy note 4. I have files and pictures that are needed.off this phone..someone..please.advise

no your files are gone unless you are able to connect the old motherboard while still in phone and the phone is able to go in to download mode by pressing volume up, home button and power button at same time while phone is off for a couple of seconds. then you would be able to get the files off

Hi.. I need help. where can I order a motherboard of my Note 4? I need to replace it coz its defective. I bought my Note 4 from Singapore. And what are the serial numbers that I need to take note before I order a motherboard so that it would be compatible of my Note 4 that I bought from Singapore. Please comment. Thanks for your help guys.

Pls m Samsung note 4 fell on the floor.nd after den the phone ve been heating up.I can no longer play music with my phone.....I can't takeep calls with it cos I won't be hearing wat the person is saying. Pls wat explanation can we give that

My phone turned off during an update install bc it was on a power loop. Now it doesnt turn on. If i swap the motherboard will it be able to come back to life and be reconnected to sprint? Any help is appreciated thanks

Anyone else replace one of these and get a "no sim card found" error? Everything else on the new board works, including WIFI. It also mentions that the sim card is locked. I have a SM-N910P from Sprint, and ordered a new board, which says that same thing, but I wasn't sure if unlocking the SIM card would do anything or not. All I can find online is unlocking for GSM and AT&T and such, but nothing on CDMA and Sprint.

My Samsung N910 Note 4 fell into salt water and the service center folks have indicated that the mother board as well as the LCD panel needs to be changed. This is as-good-as-buying a new phone. I can get the LCD replaced at a reasonable cost [when compared to Samsung Service Center]. The mother board is not available when I checked around. Where can I buy a N910 Note 4 mother board. Thanks.

Hello … Is there any way through which I can test a screen and see if it’s working or not before buying a new one? The situation is: One fine evening my Note 4 started getting hanged / busy… Showing busy blue notification light, I restarted it. It worked for a few hours, but ultimately became dead. One repair guy told me that it’s Motherboard issue, however, another said it’s the display which is not working. However both of them failed to make it work again!

If your phone is charging, the charging LED will be lit. If not, start there, could be charging port, cable, wall brick, or motherboard. If it's charging, and your phone vibrates when you power it on, but nothing at all happens on the display, it's most likely either the screen or the power connector to the screen has gone bad, which could be screen or motherboard. If it is charging but doesn't vibrate when you try to power it on, it’s most likely the motherboard.

Other than that, unless you have a variety of electronics tools at your disposal like a breadboard, multimeter, and circuitry components, there's not really any way I know of to test the screen without removing it from the phone and hooking it up to something else.

It also could just as easily be that the connection came unplugged and it's just a matter of reinserting a flex cable on the motherboard.
